Answer:
b = (d-c)/a
Step-by-step explanation:
ab + c = d
We want to solve for b, so we need to get b alone
Subtract c from each side
ab+c-c = d-c
ab = (d-c)
Divide each side by a
ab/a = (d-c)/a
b = (d-c)/a
Answer:
Call the number x and y. Then:
x - y = 45
and
x/y = 4, So x = 4y
Substitute 4y for x in the first equation:
4y - y = 45
3y = 45
y = 45/3 = 15
Substitute y = 15 in the first equation
x - 15 = 45
x = 45 + 15 = 60
So the two numbers are 60 and 15

Answer:
X Y
-5 7
-2 1
-1 -1
2 -7
Step-by-step explanation:
If x = -5, then:
y = -3 -2(-5)
y = -3 + 10
y = 7
If x = -2, then:
y = - 3 -2(-2)
y = -3 + 4
y = 1
If x= -1, then:
y = -3 -2(-1)
y = - 3 + 2
y = -1
If x=2, then:
y = -3 -2(2)
y = -3 -4
y = -7
