Today Mr. Harbeck taught us about two-step algebra.
A normal two-step question should look like...
Coefficient(variable)+constant=answer
4y-9=15 4y 24
4y-9+9=15+9 4 = 4
4y=24
y=6
Verify to check
Let y=6
4y-9=15 4(6)-9=15
15=15
An out of order question may look like...
-69=7v-6 rewrite it in order
7v-6=-69 7v = -63
7v-6+6=-69=6 7 7
7v=-63
v=-9
Verify to check
let v = -9
-69=7v-6
-69=7(9)-6
-69 = -69
