Answer:
-9/7
Step-by-step explanation:
Put the equation into y = mx + b form, by first isolating y:
9x + 7y= 7
7y = -9x + 7
Divide each side by 7:
y = -9/7x + 1
So, -9/7 is the slope.
Y = 5 - 3x....so sub in 5 - 3x for y in the other equation
5x - 4y = -3
5x - 4(5 - 3x) = -3.....distribute the -4 thru the parenthesis
5x - 20 + 12x = -3...add 20 to both sides
5x + 12x = -3 + 20...combine like terms
17x = 17...divide both sides by 17
x = 17/17
x = 1
now sub 1 in for x into either of the original equations to find y
y = 5 - 3x
y = 5 - 3(1)
y = 5 - 3
y = 2
check...
5x - 4y = -3
5(1) - 4(2) = -3
5 - 8 = -3
-3 = -3 (correct)
so ur solution is (1,2)
Answer:
the answer is 7x + 437
Step-by-step explanation:
1) 7 is the only number with a variable, <em>x</em>, so it will remain as it is.
2) -4+4= 0
3)1+1= 2
4) 2+435= 437
7) combine 7x and 437 together. 7x + 437.
We cant go any further, because 7x and 437 are not liketerms.
