Jasmine decides to solve this system of equations using the substitution method.
3x + y = 18
4x + 2y = 10
These are the first two steps of the method that Jasmine will use.
Step 1: Solve for y in the first equation.
Step 2: Substitute the result from Step 1 into the second equation.
Which equation should be solved in Step 3 using Jasmine's method?
O A 4x + 18 + 3x = 10
B. 4x + 18 - 3x = 10
C. 4x + 36 - 3x = 10
D. 4x + 36 + 6x = 10
E 4x + 36 - 6x = 10

Answer:

Make x the same in both so

12x+ 4y=72

12x+6y=30

Now the 12x cancel eachother out so

Difference between 6y and 4y is 2y

Difference between 30 and 72 is -42

2y must equal -42

Y = -21

Substitute -21 into the equation

X = 13
