Q.1 x-2/5=7
divide -2/5 which is -0.40
x-0.40=7. Move -0.40 to the right side of the equal sign and that becomes +0.40
x=7+0.40 . 7+0.40 is 7.4
x=7.4
Q.2 2.1r=6.174
divide 2.1 by both sides which 2.1r divided by 2.1 is 1r and 6.174 divided by 2.1 is 2.94
r=2.94
Q.3
equation: 2/3 = 32 2/3 d
Q.4 x9=3/5
3/5 is 0.60
x9=0.60
divide 9 by both sides. 9x divided by 9 is 1x and 0.60/9 is
0.0
6666 (the 6 is continuing)
x=0.06666
Q.5
x=-3
Q.6
7.25 =0.5x
divide 0.5 by both sides. 0.5x divided by 0.5 is 1x and 7.25 divided by
0.5 is 14.5
x=14.5
Q.7

Question 3: y = 60
Question 4: w = 496
Question 5: Kyle had $400 to begin with.
Step-by-step explanation:
Question 1 explanation: 12g = 72 ⇒ g = = 6
Question 2 explanation: = 21 ⇒ v = 21 * 4 = 84
Question 3 explanation: y = 10 ⇒ 6 * y = 10 * 6 ⇒ y = 60
Question 4 explanation: w + 376 = 872 ⇒ w = 872 - 376 = 496
Question 5 explanation: K - 85 = 315 ⇒ K = 315 + 85 = 400, so Kyle had $400 originally in his account.
