Answer:
Step-by-step explanation:
The simaltaneous equation are:
● 3a + 2b = 6
● 3b - 2a = 10
Graph both equations
While graphing use x instead of a and y insread of b in the graphing tool
The solutions are the coordinates of the intetsection point between the two lines.
The intersection point coordinates are approximatively (-0.15,3.2) picture below
Wich means:
● x = a = -0.15
● y = b = 3.2
Step-by-step explanation:
3a+2b=6
3b-2a=10
3a+2b=6 multiply by 3
-2a+3b=10 multiply by 2
9a+6b=18
-4a+6b=20 (-)
13a= –2. divide b.s by 13
a= –2/13
3b-2a=10
3b-2(-2/13)=10
3b+4/13=10
3b=10-4/13
3b=126/13. divide b.s by 3
b=42/13
