Answer:
(2, 4.5 )
Step-by-step explanation:
Given the 2 equations
6x + 4y = 30 → (1)
5x - 2y = 1 → (2)
Multiplying (2) by 2 and adding to (1) will eliminate y
10x - 4y = 2 → (3)
Add (1) and (3) term by term to eliminate y
16x + 0 = 32
16x = 32 ( divide both sides by 16 )
x = 2
Substitute x = 2 into either of the 2 equations and solve for y
Substituting into (1)
6(2) + 4y = 30
12 + 4y = 30 ( subtract 12 from both sides )
4y = 18 ( divide both sides by 4 )
y = 4.5
solution is (2, 4.5 )
Answer:
<u>The correct answer is B. 9</u>
Step-by-step explanation:
Let's solve for y in the equation below, given that x = 2
y = 6x - 3
Substituting x in the equation, this way:
y = 6 * 2 - 3
y = 12 - 3
y = 9
The value of y is 9 when x is 2
<u>The correct answer is B. 9</u>
