How do you translate sentences into equations?
To translate sentences into equations, identify the missing number as 'x' and represent phrases like '3 times a number' as '3x'. For example, '5 more than 3 times a number is 26' translates to '3x + 5 = 26'. Solve the equation to find the value of x.
What is the equation for '26 less than 5 times the number is 9'?
The equation for '26 less than 5 times the number is 9' is '5x - 26 = 9'. Solve this equation to determine the value of x.
How do you convert 'the difference between 4 times a number and 7 is 5' into an equation?
To convert 'the difference between 4 times a number and 7 is 5' into an equation, use '4x - 7 = 5'. Solve this equation to find the value of x.
What is the equation for '7 more than the quotient of a number and 3 is 10'?
The equation for '7 more than the quotient of a number and 3 is 10' is 'x/3 + 7 = 10'. Solve this equation to determine the value of x.
How do you express '5 less than 3 times the sum of a number and 4 is 22' as an equation?
To express '5 less than 3 times the sum of a number and 4 is 22' as an equation, use '3(x + 4) - 5 = 22'. Solve this equation to find the value of x.

Translating Sentences into Equations: Solving for 'x'
- To translate sentences into equations, start by identifying the missing number as 'x' and representing '3 times a number' as '3x'.
- For the equation '5 more than 3 times a number is 26', convert it to '3x + 5 = 26' and solve to find x = 7.
- In the equation '26 less than 5 times the number is 9', convert it to '5x - 6 = 9' and solve to find x = 3.
- To convert 'the difference between 4 times a number and 7 is 5' into an equation, use '4x - 7 = 5' and solve to find x = 3.
- For '7 more than the quotient of a number and 3 is 10', the equation is 'x/3 + 7 = 10', solved to find x = 9.
- In '5 less than 3 times the sum of a number and 4 is 22', the equation is '3(x + 4) - 5 = 22', solved to find x = 5.
