Answer 1

$\color{blue}{ANSWER}$

We will bring like teams together in every answer, we get

(a) 5x - 2x + 7 = x + 1

$5x - 2x - x = 1 - 7$

$5x -3x = -6$

$2x = -6$

$x = - 6 \div 2$

$x = - 3$

(b) x + (x+2) = (x + 4) +31

$x + x - x= 4 +31 + 2$

$x = 37$

(c) 2(m + 7) = 3(m - 10)

$2m + 14 = 3m - 30$

$2m - 3m = - 30 - 14$

$- m = - 44$

$m = 44$
