solve for a
7a - 2b = 5a + b
a = 2b
a = 3b
a = 3/2b
a=2/3b

Therefore solution for a is

Step-by-step explanation:

Given:

7a - 2b = 5a + b

To Find:

a = ?

Solution:

7a - 2b = 5a + b    .................Given

First take all the 'a' terms to the left hand side and 'b' terms to the right-hand side of the equation,

∴

Now dividing by 2 on both the side we get

∴

Therefore solution for a is

multiply then divide

step-by-step explanation:

hi there

the slope is 1/3.

this is because from the y-intercept, you go up one, and you go to the right three, to get to the next exact point on the graph. this is known at the “rise over run.”

p.s. (if you need it).your y-intercept is -2, because that is the point on the graph where the line crosses the y-axis.

hope that : )
