Solve the equation
2.9=7.1 + y
2 answers:
Answer:
y=-4.2
Step-by-step explanation:
2.9=7.1+y
2.9-7.1=7.1-7.1 +y
-4.2=y or y= -4.2
y = -4.2
If you substitute that value for <em>y</em> into the equation, you'll get 2.9 = 7.1 + (-4.2)... and that is a correct, valid equation. <em>HOPE THAT HELPS!</em>
