Answer:
d=-4
Step-by-step explanation:
1.5d+9.75=1+2.75
1) Combine alike terms on the right side of the equation:
1.5d+9.75=3.75
2) Subtract 9.75 from both sides:
1.5d=-6
3) Divide both sides by 1.5:
d= -4
1.5d + 9.75 = 1 +2.75
simplify the right hand side:
1 + 2.75 = 3.75
you get:
1.5d + 9.75 = 3.75
isolate 1.5d, subtract 9.75 on both sides:
1.5d = -6
divide by 1.5 on both sides to get d by itself:
