How to solve this equation algebraically: Y=2x+1 3x+4y=26

You can substitute what y is into the second equation, so:
3x + 4(2x + 1) = 26
3x + 8x + 4 = 26
11x + 4 = 26
- 4
11x = 22
÷ 11
x = 2

y = (2 × 2) + 1
y = 5 + 1
y = 5

So you get x as 2 and y as 5, I hope this helps!

Solve for H: A = L ⋅ W ⋅ H
Sergeu [11.5K]

Answer:

The answer would be

H = A over L times W

Step-by-step explanation:

This is because, when you multiply the L, W, and H you end up getting A. This means that A is the biggest number. We automatically can tell that H is what were looking for so putting those two things together we have this: H = A over ???

The ??? would have to be L times W because those are the only things left and they get multiplied together which in the end leaves us with

H = A over L times w

aka

H=A/LxW
