The solution of 2x -3=7

x = 5

Step-by-step explanation: To solve for x, we must first isolate the term containing x which in this problem is 2x.

Since 3 is being subtracted from 2x, we add 3

to both sides of the equation to isolate the 2x.

On the left, the -3 and +3 cancel

out and on the right, 7 + 3 is 10.

So we have 2x = 10.

No we can finish things off by just dividing

both sides of the equation by 2.

On the left the 2's cancel and on

the right, 10 divided by 2 is 5.

So we have x = 5.

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
