A=andy's age
b=belinda's age
3a=11+2b
a+b=-2+2b
wowie
a+b=-2+2b
minus b from both sides
a=b-2
subsitute b-2 for a
3a=11+2b
3(b-2)=11+2b
3b-6=11+2b
minus 2b from both sides
b-6=11
add 6 to both sides
b=17
subsitute
a=b-2
a=17-2
a=15
andy is 15
belinda is 17
Answer:
Both equations have the same solutions.
Step-by-step explanation:
Please consider the complete question:
Determine whether or not the two equations below have the same solution. In two or more complete sentences, explain your rationale.
Let us solve our 1st equation as:
Now, we can see that equation (1) turns out same as equation (2), therefore, both equations will have the same solution.
Answer:
3x - 4 = 32
Step-by-step explanation:
We solve for x to find the number (knowing that x is the unknown number).
3x - 4 = 32
3x = 32 + 4
3x = 36
x/3 = 36/3
x = 12
