What is 22 + 5d = -8(7d-4)
2 answers:
22+5d=-8x7d=56d+ -8x-4=32
22+5d=-56d+32
22+32=54 and -56d+5d=-51d
The answer would be 51d+54
Remark
The steps are the same usually. Remove the brackets and collect like terms on each side of the equal sign.
Solution
22+5d = -8(7d - 4) Remove the brackets.
22+5d = -56d + 32 Notice the sign change on 32. 2 minus quantities = a plus when multiplied. Add 56d to both sides.
22 + 5d + 56d = - 56d + 56d + 32
22 + 61d = 32 Subtract 22 from both sides.
61d = 32 - 22
61d = 10 Divide by 51
d = 10/61
d = 0.1639 Answer
Check
<em><u>LHS</u></em>
22 + 5*0.1639 = 22.8197
<em><u>RHS</u></em>
-8(7*0.1639 - 4)
-8(1.1473 - 4)
-8(-2.8527)
22.8216
The difference is a rounding error.
