GREYUIT [131]3 years ago

Try seeing the problem as
-2(y) + x(-3)
If you plug in 3 in place of y, you’ll get
-2(3) + x(-3).
If you solve the first half of the equation, you’ll be left with
-6 + x(-3)
Repeat this step with x, by plugging in -5 in place of x
-6 + -5(-3)
A positive * a positive = a negative, so your equation should look like
-6 + 15
If you flip it around, you’ll be left with a simple problem, and answer
15 - 6 = 9

GrogVix [38]
Let x be the no. of seconds it takes for the balloons to be at the same height.
7+3x = 12+2x
Deduct both sides by 2x.
7+x = 12
Deduct both sides by 7.
x = 5
Ans: It will take 5 seconds for the balloons to be at the same height.

insens350 [35]

Answer:

x = 8

Step-by-step explanation:

10x - 2 (x + 6) = 52

Let X become 8

10 (8) - 2 (8 + 6) = 52

80 - 2 (14) = 52

80 - 28 = 52

52=52
