Answer:
10
Step-by-step explanation:
We can write the equation 38=4y-2 because LZ and DO are equivalent
Isolate x:
38=4y-2
38+2=4y-2+2 (add 2, addition property of equality)
40=4y
40/4=4y/4 (divide by 4, division property of equality)
10=y
Subtract both sides by 7
We have to make sure that we isolate the x term first. So we must subtract 7 from both sides.
