The given equations are:
5x - 2y = 88
3x + 4y = 58
Multiplying the 1st equation by 2, we get the new set of equations as:
10x - 4y = 176
3x + 4y = 58
Adding the two equations, we get:
10x - 4y + 3x + 4y = 176 + 58
13x =234
x = 18
Using the value of x in 1st equation, we get:
5(18) - 2y = 88
- 2y = 88 -5(18)
-2y = -2
y = 1
So, the solution of the equation is (18, 1)
solve for "y" so it is in the form y = mx + b. "m" is the slope and "b" is the y-intercept.
ax + by = c
by = -ax + c <em>subtracted "ax" from both sides</em>
y = (-a/b)x + c/b <em>divided both sides by "b"</em>
Answer: slope is -a/b and y-intercept is c/b
First, take about the
and
You can cancel out the two 3's on the bottom using two of the threes from the numerator
Simplify the fraction
3 x 3 Multiply
9
So first, i like to answer the question first. 17 times 6 = 102. So you can use 1 100 model/block and 2 ones :)
Answer:
15x + 7
Step-by-step explanation:
8x + 16 + 7x - 9 =
15x + 7
Hope that helps!
