Question

3t + 2b = 9
1t + 2b=7
solve for t and b (:

Answer 1

Are these two different equations? or both in one

Answer 2

both in one

Answer 3

ok

Answer 4

Just convert any variable in terms of other n solve by method of substitution

Answer 5

multiply the second equation by -1 and then use elimination method

Answer 6

Like t=7-2b

Answer 7

so t=1 and b=3?

Answer 8

Step 1: Solve2b+t=7for t:
2b+t+−2b=7+−2b(Add -2b to both sides)
t=−2b+7
Step: Substitute−2b+72b+3t=9:
2b+3t=9
2b+3(−2b+7)=9
−4b+21=9(Simplify both sides of the equation)
−4b+21+−21=9+−21(Add -21 to both sides)
−4b=−12 −4b −4=−12/−4
(Divide both sides by -4)b=3
Step: Substitutet=−2b+7:
t=−2b+7
t=(−2)(3)+7
t=1(Simplify both sides of the equation)

Answer 9

b=3 and t=1
