Question

please send me the working​

Answer 1

Step-by-step explanation:

Q1:

1) 7m-2[6m-(3m-4p)]

   7m-2[6m-3m+4p]

   7m-2×6m+2×3m-2×4p

   7m-12m+6m-8p

   m-8p

$2) \frac{x+5}{3} -\frac{(2x-7)}{6}+\frac{x}{2}\\\\ \frac{2(x+5)}{6}-\frac{(2x-7)}{6}+\frac{3x}{6} \\\\ \frac{2(x+5)-(2x-7)+3x}{6}\\\\\frac{2x+10-2x+7+3x}{6}\\\\\frac{17+3x}{6}\\\\\frac{3x+17}{6}$

Q2.

1) 2x-3(5-x)=35

  2x-15+3x=35

  5x-15=35

  5x=35+15

  5x=50

  x=10

$2) \frac{x-3}{3} = \frac{4x-5}{4} \\\\ 4(x-3)=3(4x-5)\\\\ 4x-12=12x-15\\\\ 15-12=12x-4x\\\\ 3=8x\\\\ x=\frac{3}{8}$
