Question

Can someone help me with Question 1, a-b of this assignment? I'd deeply appreciate it! :) I am trying to figure these questions out, and I need help.

Answer 1

Explanation:

i think i answered another question by you but ill help anyways

ok so you are trying to check the fact that x=2 for both equations

for A. by using substitution

and B. by properties of Equality

A is easy you just substitute 2 into the x values in the given equations

it will look like

-3x+14=18-5x

-3(2)+14=18-5(2)

-6+14=18-10

8=8

and

2x=5-1/2x

2(2)=5-1(2)/2

4=5-2/2

4=5-1

4=4

so now we have proved that both x are eual to 2 by using substitution

i already answered b on a different question
