Answer:
x = 7
y = -2
Step-by-step explanation:
4x + 3y = 22 ---------------------(I)
5x - 4y = 43 ---------------------(II)
Multiply(I) by 4 and equation (II) by 3. And then add the equations
(I) * 4 16x + 12y = 88
(II) *3 <u>15x - 12y = 129</u> {Add & thus y will be eliminated}
31x = 217
x = 217/31
x = 7
Plug in the value of x in equation (I)
4*7 + 3y = 22
28 + 3y = 22
3y = 22 - 28
3y = -6
y = -6/3
y = -2
Answer:
(13c-5b)(a+4)
Step-by-step explanation:
Since both (13c) and (-5b) are being multiplied by (a+4), we can factor both of them out and put them in a bracket.
13c(a+4)−5b(a+4) = (13c-5b)(a+4)
Answer:
y=2x-4
Step-by-step explanation:
slope=2=k
y-intercept in - 4 then n=-4
y=kx+n
y=2x-4
