Question

Afla termenul necunoscut:
m-236x3=292
332x3-m=599
m+118x6=900
436x2-m=297
900+2-a x 100 =302
a x(57 -13x4)=340
(m x 2 -40):23=12

Answer 1

m-236×3=292
m-708=292
m=292+708
m=1000

332×3-m=599
996-m=599
m=996-599
m=397

m+118×6=900
m+708=900
m=900-708
m=192

436×2-m=296
872-m=296
m=872-296
m=576

900+2-a×100=302
902-a×100=302
a×100=902-302
a×100=600
a=600÷100
a=6

a×(57-13×4)=340
a×(57-52)=340
a×5=340
a=340÷5
a=68

(m×2-40)÷23=12
m×2-40=12×23
m×2-40=276
m×2=276+40
m×2=316
m=316÷2
m=158
