Answer:
(-3, -7)
Step-by-step explanation:
y = 4x + 5
y = x - 4
add 4 to both sides of the second equation to get y + 4 = x
plug that back into the equation to get y = 4(y + 4) +5
distribute to get y = 4y + 16 + 5
combine like terms y = 4y + 21
subtract 4y on both sides to get -3y = 21
divide both sides by -3 to get y = -7
plug -7 into the second equation to get -7 = x - 4
add 4 on both sides to get -3 = x
therefore (-3, -7)
Hey there! :D
y=2x-9
We can plug that in as y, since y is equal to 2x-9.
5x-3(2x-9)= 23
Distribute.
5x-6x+27= 23
-1x+27=23
Subtract 27 on both sides.
-1x=-4
Divide both sides by -1.
x=4
Now, plug that in for y.
y=2(4)-9
y=8-9
y=-1
(4,-1) <== solution
I hope this helps!

For clearly look we can seperate the number parts and the letter parts because they are all “*” and “/“ caculation
Initial fraction: (20 * a^2 * b) / ( 5 * a * b^2) = (20 / 5) * (a^2 / a) * (b / b^2)
Result: (4*a) / (b) = (4*a) / (1*b) = (4/1) * (a/b)
As you can see the result is a fully simplifying form so just simplify any thing you can from initial fraction
20/5 = 4/1 (both nume and deno are divided by 5)
a^2 / a = a/1 (divided by a)
b / b^2 = 1/b (divided by b)
Multiply all above we get the result 4a/b (just for checking whether we did right or not)
Next, multiply all that we have divided in previous step: 5*a*b = 5ab
=> problem solved
