Answer:
x = 2, y = 3
Step-by-step explanation:
Given the 2 equations
3x + 4y = 18 → (1)
5x + 6y = 28 → (2)
Multiplying (1) by 5 and (2) by - 3 , then adding will eliminate the term in x
15x + 20y = 90 → (3)
- 15x - 18y = - 84 → (4)
Add (3) and (4) term by term to eliminate x
2y = 6 ( divide both sides by 2 )
y = 3
Substitute y = 3 into either of the 2 equations and solve for x
Substituting into (1)
3x + 4(3) = 18
3x + 12 = 18 ( subtract 12 from both sides )
3x = 6 ( divide both sides by 3 )
x = 2
Solution is (2, 3 )
Distribute the 10 and 15 through the parenthesis
10(x + 4) + 15(x + 1)
10x + 40 + 15x + 15
25x + 55
Answer:
Step-by-step explanation:
1/3Bh
1/3[1/2(10x20)](19)
1/3(100)(19)
1/3(1900)
633 1/3
The answer is (3,3) point to X move up four times than to the left 2 times
