2x+2y=38
y=x+3

First you would substitute the y for x+3
2x+2(x+3)=38

You would multiply the 2 by the x+3
2x+2x+6=38

Add the 2x and the 2x
4x+6=38

Subtract the 6 on both sides
4x=32

Divide the 4 on both sides
x=8

Now substitute the x in the second problum for 8
y=8+3

Add the 8 and the 3 to solve for y
y=11

Your answers
x=8
y=11
the correct answer would be A:(8,11)

8 jumbo blueberry muffins ... 1 1/2 teaspoons of baking powder
3000 jumbo muffins ... x teaspoons of baking powder = ?

8 * x = 1 1/2 * 3000
8 * x = 3/2 * 3000
8 * x = 4500

Put the following equation of a line into slope-intercept form, simplifying all fractions 2x + 6y = 36​
joja [24]

Answer:

y=-\frac{1}{3} x+6

Step-by-step explanation:

Slope intercept form is y=mx+b. So, you solve for y by putting x to the other side and dividing by 6. In order it looks something like:

2x+6y=36
2x -2x +6y = 36 =2x
6y=36-2x

y=6-2/6x
y=6-1/3x
