200/1.8
\
<em>26</em>
- Step-by-step explanation:
<em>- 4x + 3y + z =</em>
<em>= -4(-5) + 3(2) + 0</em>
<em>= 20 + 6 + 0</em>
<em>= 26</em>

I guess you want to find the values of x & y. If so:
7x+2y=24
8x+2y=30
1) multiply the 1st equation by (-1)==> -7x-2y=-24
2) Now add -7x-2y=-24 to 8x+2y=30 ==> x + 0y = 6 ==> x = 6
3) replace x by 6 in any of te two equation & you will find y= - 9
