Step-by-step explanation:
by having two equations that have the same point, you can set the two equations equal to each other
y = 12x + 3, y = x + 1
12x + 3 = x + 1
11x = -2
x = -2/11
when you find the the x value, plug it back into either one of the equations
y = x + 1
y = (-2/11) + 1
y = 11/11 - 2/11
y = 9/11
the point (solution):
(-2/11, 9/11)
Answer:
x=5
Step-by-step explanation:
2x-3+4x=27
6x-3=27
6x=27+3=30
x=30/6
x=5
Answer:
elimination method
Step-by-step explanation:
2) 4y+4x=8;y+2x=4
4y+4x=8. ------(1)
y+2x=4 -------(2)
multiply equation (1) by 2 and (2) by 4 to eliminate x
8y+8x=16
4y+8x=4
Answer:
-76.07
Step-by-step explanation:
-24-(41.07+11)
-24-1(41.07+11)(the next step is distributive property which is multiplying everything in the parentheses by the thing connected to it in this case, -1)
-24-41.07 + 11
-24-41.07-11
-76.07
Answer:
5800 x 0.0135 = 78.3
78.3 x 3 =234.9
78.3/2 = 39.15
234.9 + 39.15 = 274.05
Your answer is 274.05
Step-by-step explanation:
Hope this helps!
