The "answer" is the number that 'x' must be in order to make the statement true.
Here's a way to find out what the number is:
-42 = 7 + 7x
Subtract 7 from each side of the equation:
-49 = 7x
Divide each side by 7:
-7 = x

7x + 9 = 51 7x = 42 x = 42/7 = 6
7x plus 7 equals 28 x equals?
7x+7=28x 28x-7x=7 21x=7 x=3
6 plus 7x equals -36?
6 + 7x = -36 first, subtract 6 from both sides 7x = -42 then, divide both sides by 7 7x/7 = -42/7 x = -6 to check, put -6 back into the original equation: 6 + (7 x -6) = -36 6 - 42 = -36
Resolve -7x equals -49?
42
What is -7x plus 10 equals 52?
- 7X + 10 = 52 subtract 10 from each side - 7X + 10 - 10 = 52 - 10 - 7X = 42 divide both sides integers by - 7 (- 7/- 7)X = 42/- 7 X = - 6 --------------------check in original equation - 7(- 6) + 10 = 52 42 + 10 = 52 52 = 52 ----------------checks
