Step-by-step explanation:
1. 3x + 4 = 19
3x = 15
x = 5
2. 7 + 2x = 15
2x = 8
x = 4
Answer:
7/12
Step-by-step explanation:
3*4=12. 4/12+3/12=7/12.
57.80 - 4.07
= 57.80 - 4.00 - 0.07
= 53.80 - 0.07
= 53.73
Answer:
x is an unknown quantity whose value is determined based on any algebraic equation it is used in.
Step-by-step explanation:
Answer:
y = 3x+3
Step-by-step explanation:
we can find the equation of the line with this formula:
y-y1 = m(x-x1) where y1 and x1 indicate the coordinates of the given point and m the slope
so we have
y-9 = 3(x-2)
y = 3x-6+9
y = 3x + 3
