Answer:
(0.5, 4 )
Step-by-step explanation:
Given the 2 equations
2x + 3y = 13 → (1)
4x - y = - 2 → (2)
Multiplying (2) by 3 and adding to (1) will eliminate the term in y
12x - 3y = - 6 → (3)
Add (1) and (3) term by term to eliminate y
14x = 7 ( divide both sides by 14 )
x = 0.5
Substitute x = 0.5 into either of the 2 equations and evaluate for y
Substituting into (1)
2(0.5) + 3y = 13
1 + 3y = 13 ( subtract 1 from both sides )
3y = 12 ( divide both sides by 3 )
y = 4
Solution is (0.5, 4 )
Answer:
ratio compare
Step-by-step explanation:
thats why
Answer:different of two squares states that
If a²-b² is given then
a²-b²=(a+b)(a-b)
Now to answer the question
(x+2)²-(x)²=68
(x+2+x)((x+2)-x)=68
(2x+2)(x+2-x)=68
(2x+2)(2)=68
Divide both sides by 2
{(2x+2)(2)}÷ 2 = 68/2
2x+2= 34
Collect like terms
2x=34-2
2x=32
Divide both sides by 2
2x/2 =32/2
x=16
Hence
x=16
x+2=16+2=18
The two consecutive even integer are 16 and 18
