Question

Given that

R
=
3
x
+
2
y

Find
x
when
y
=
7
and
R
=
8

Answer 1

-2

Explanation:

Hey there!!

if we evaluate the expression it will look like :

3x + 14 = 8

and if we solve it:

3x+14=8

Step 1: Subtract 14 from both sides.

3x+14−14=8−14

3x=−6

Step 2: Divide both sides by 3.

3x/3 = -6/3

x= −2
